FLASK-BAR.

Application filed July 29,

To all whom it may concern y Be it known that I, RoYnR S. BUOH, a citizen of the United States, residing at York,

in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Flask-Bars, of which the following is a specification.

One object of my invention is to provide an improved flask bar which can be used with advantage in connection with inolders flasks for assisting in supporting the sand in the flasks.

Another object is tomake my improved flask bar of a simple and durable construction and so that it can be easily made and attached to a flask.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which?- Figure 1 is a top plan view showing a flask having my improved bars attached thereto,

Fig. 2 is a section taken on the line 2-2 of Fig. 1,

Fig. 3 is a section taken on the line 33 of F ig. 1, l l

. Fig. 4 is a fragmentary perspective view of one of my improved flask bars,

Fig. 5 is a view of similar nature to Fig. 1 showing a modified form of my flask bar,

Fig. 6 is a section taken on the line 6-6 of Fig. 5,

Fig. 7 is a section taken on the line 77 of Fig. 5, and

Fig. 8 is a fragmentary perspective view of one of the flask bars shown in Figs. 5 to 7 inclusive.

Referring to Figs. 1 to 4 of the drawings, 9 represents a flask having two of my improved bars 10 connected thereto and extending across the flask. Each of these flask bars is made up of two sections or plates 11 and 12. The plates 11 and 12 are corrugated lengthwise as shown at 16, said corrugations providing projecting ribs 14: and grooves 15. The plates 11 and 12 are split or cut at intervals along their edge portions. The cuts or splits extend from the edges in the direction of the width of the plates to provide tongues 16 and 17 which alternate with each other, as clearly shown in Fig. 2. The tongues 17 are substantially fiat, as clearly shown in Figs. 3 and ft, and the plates 11 and 12 are positioned side by side; the tongues 17 of one plate abutting the Specification of Letters Patent.

tongues 17 of the other plate, both at the top and bottom of said plates. Rivets 18 extend through each set of the contacting tongues 17 and thereby bind the plates 11 and 12 together. The alternating sets of tongues -16flare apart and form troughs or cradles, such as illustrated at 19. The plates 11 and 12 are so arranged that the ribs of one plate are directly opposite the ribs of the adjacent plate, and the grooves.

of one plate are directly opposite the grooves of the other plate, as is clearly shown in Fig. 3. The bars are preferably secured to the flask 9 by providing cars 20 at the ends and bending them at an angle to permit bolts 21 to extend therethrough and through the flask. It will thus be noted that by providing the corrugated plates as above/described and alternating the tongues 16 and 17 that a good bearing is provided for. the sand which is placed in the flask for the molding operation so as to support the sand between the sides and ends of the flasks Furthermore by splitting the plates to provide the tongues, portions of the sand will be wedged between the adjacent edges of the tongues 16. Also by having the tongues at the bottom as well as at the top of the bars, the sand will be held closely to the object being molded and thereby prevent any distortion or movement of the sand; during the molding operation.

In the form of my invention shown in Figs. 6 to 8 inclusive each of theflask bars 10 is made of a single piece or plate, such for example as steel, which is also corrugated as shown at 22 andthis plate at its top and bottom is split to provide alternating tongues 23 and 24:; said tongues being.

flared outwardly to cause the sand to be wedged between them and within the spaces provided by the splits 25. In this instance, the plate is preferably provided with cars 26 through which bolts 27 extend for securing them to the flask 28.

By making my improved flask bars as above described they can be quickly made from sheets of steel and stamped out and do not require the addition of separate elements to provide sand retaining elements, such as are present in numerous sand supporting bars made prior to my invention.

By making the plates as illustrated and above described, the corrugations can be pressed and rolled therein and these corrugations provide wavy opposite sides of the Patented July 27,1920.

bar which serve to support the sand and. at the same time the sand can be readily removed therefrom.

While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims. I v

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A flask bar including a plate having portions split so as to provide tongues, said tongues being bent laterally therefrom; substantially as described.

2. A flask bar including a plate having an edge portion provided with tongues bent therefrom; and other. tongues betweensaid first tongues and out of line therewith; substantially as described.

'3. The combination with a flask of a bar including a plate having edge portions split to provide tongues, said tongues being bent laterally therefrom; and means at the ends of said plate for connection with opposite sides of said flask; substantially as described.

4. .A flask bar' including a corrugated plate having tongues bent therefrom; substantially as described.

'5. A flask bar including two plates secured together, said plates having tongues bent in opposite directions; substantially as described.

6. A flask bar including two plates, said plates having tongues spaced apart and bent in opposite directions; other tongues on said plates; and means for-securing said apart and bent in opposite directions; otherv tongues on said plates; and means for securing said latter tongues together; -substan tially as described.

10. A flask bar including two corrugated plates,-said plates having tongues spaced apart and bent in opposite directions; other tongues on said plates; and means for securing said latter tongues together, said latter tongues being positioned'between said first tongues; substantially as described. v 11. A flask bar including a, plate having corrugations which extend in the direction of the length thereof transversely of the flask; substantially as described.

12. A flask bar including a plate having corrugations pressed thereinso that the grooves of the corrugations on one side form the ribs of the corrugations on the opposite side of said plate; substantially as described.

In testimony whereof I have signed my name to' this specification in the presence of two subscribing witnesses.
